If your ECM is already damaged, this tool will not fix it. Is this the replacement ECM? The pictures show that it isn't connecting.

Now you're really getting somewhere. You could have the PCM automatically activate rear defrost if engine coolant temp is below 50F. And then have the horn activate as a shift "light" once a...

0.5.3 tested fine on my bench harness with a B-body tune. I'll email you a log in case you're interested.

Flash hack 0.5.0 passes bench test on my B-body bin with no change in settings. No errors.

Testing B.0.4.2 worked fine on my bench, no errors. Emailed you a log. Take a break!

Thinking big picture, if the sledgehammer method works for now, there's more value add to be had in other areas. Smash away and move on.

No worries, just have the user disconnect the cable.

steveo, some thoughts:
1. Having high latency is not a unique problem to this interface; it happens in all sorts of applications. What if there was a way to determine the latency? Without being...

Maybe midday tomorrow. The car currently has nothing more than manifolds, no cooling system, accessories or transmission. I cobbled it together enough to start it and verify oil pressure, ignition...

What's amazing is that I've flashed literally dozens of B-body tunes through this exact same interface and NEVER had a brick with eehack.

Summary:

1. Read with no errors.
2. Wrote with no...

Quick update, in chronological order:
1. flashhack refuses to read (although it read this PCM once last night).
2. eehack reads just fine.
3. flashhack writes just fine.

I'll take further debug...

That's what i get for trying to flash WAY past my bedtime. Gibberish and noisy bus traffic, hah.

Yeah I'll give it a whirl. This looks like a B-body BIN all right. I wonder what would happen if...

I may have not saved the actual log of where it hosed on the T side in the first place.

EDIT - just read your post. Huh. Maybe it's fine. This is a new-to-me PCM that looks like it was out of a...

Steve, sent you an email. I tried an OBD1 PCM hooked up into a '96 B-body with a new (to me) adapter hooked to pins 9 and 5 but couldn't make it work. So I pulled the PCM out and hooked it to my...
